10 I I v UNITED STATES PATE OF RUDOLPH M. ANDERSON, or NEW YORK,:N. Y.

MOVING-PIGTUBE-FILM REEL.

Application filed March 23, 1917. Serial No. 157,049.

' To all whom iii may, concern Be it known that I, RUDOLPH M. ANDER- soN,' a citizen of the United States, residing The principal object of the invention is to provide a reel of improved construction, in which the securing means whereby the side elements are held together, are soulisposed as to present a relatively smooth surface without outstanding projections.

A further object is to prov'de fastenings whereby the side elements of' the re el are constrained together and with relation to the centralhub or core. the fastenings being operable from either side of the reel, and finally, to rovide a reel of pleasing appearance, simple in' construction, and inexpensive to manufacture. a

These and other like objects are attained by the novel construction and combination of parts hereafter described and shown in the accompanying drawing. forming a material part of this, disclosure. and in which 1- Figure lis a side elevational view of a.

reel-made in accordance with the invention. Fig. 2 is an enlarged.transverse sectional view taken on line 2'2 of Fig. 1.

Fig. 3 is a similar transverse sectional view taken substantially in the same plane, but illustrating a modification in construction. v

Fig. 4|: is a fragmental plan view of the parts shown in Fig. 2.

Fig. 5 is a similar fragmental plan view of the parts shown in Fig. 3. and Fig. 6 is a similar view of a further modification.

Thereel is-comprised of two sheet metal circular disks 10, preferably formed with a beaded peripheral edge 11, and having-a plurality of openings 12 for the purpose of lightening the structure and through which the edges of the reeled material can be seen.

Radially formed ribs 14: extend 'from the. rim 11 to a raised ring 15. in which. may be formed a concentric depression 16, adapted to engage with a central core or hub 18, so that the two side disks are held in register.

In the form'shown in Figs. 1; 2 and 4, a

number of nrcuate depressions 20 are formed in the surface 16. the depressions haying a perforation 21 from. which extends a slot 2:2. permitting the shanks of the bolts or securing elements '25 to enter, while tlfe perform tions 21 are adapted to receive the heads in formed at both ends of the lzolts 25. the. saunpassing through equally spaced longitudinal openings formed in the core 18.

At the center of the disk is a through opening 28. haying a kerway 2 the opein .ing and kerway being suited to the keyed shaft upon which the reels are rotated.

Specification ofLetters Patent. Patented May 14, 1918.

The operation of assembling is as fol- The core 18. being placed in therecess 1G. formed in the disks 15. the bolts are entered. the heads zl'iresl'mg ill the arcuate ('il \'lllk 20 on one side. the opposite ends passing through the openings 21, it being understood that the disks are pressed firmly together. whereupon one of the disks is turned with relation to the other. the twisting movement causing the heads 20. protruding through the opening :21. to pass to the other end of the recesses 20. holding the disks firmly together. a i

In the forms shown in Figs. 3 and l. a somewhat similar form of construction is employed, the side plates or disks 10 being formed at the center with a recess 16, whereby the core 18 is held in adjusted position,

the core being provided with a plurality of equally spaced longitudinal passages 35 in which are inserted tubes 36,internally screwthreaded at their ends and receptive of the screws 38, the beveled heads 39 of whichare flush when within the depressed or countersunk portions 40 of the disks 16, it being understood that the length of the tubes 36 is such as to permit the countersunk portions 40 to be drawn tightly into the ends of the wooden core, the tube acting in the manner of a nut for the screws 39, the heads of which are as indicated, level or flush with 'the surrounding surface.

In the modification shown in Figs, a through bolt 42 is engaged in the core 18,

the head 43 being seated in a countersunk depression in the plate 16, a similar depression being formed in the opposite plate re- I ceptive of the nut 4-1, the construction being such as to hold the parts rigidly together.

i In order to increase the longevity of the reel, particularly with respect to the core and provide means whereby it will not rotate Having thus described my invention, what. I claim as new, and desire to secure by Let ters. Patent, is

1. In a reel, the combination with a pair of circular disks, a central annular raised seat formed in said disks, having a plurality of perforate aroua'te depressions therein, of a solid core receivable in said seats, said core having a plurality of longitudinal passages therethrough, bolts having rigid heads formed at each end engageable with the perforate arcuate depressions in said disk seats, said rods passing through the passages in said core, and means combined with said arcuate depressions for maintaining said bolts against displacement.

2. In a reel, the combination with a pair of symmetrically forined circular plates, and a core adapted to be secured therebetween, of recessed seats formed. in said plates receptive of the ends of said core, a plurality of tubes inserted at spaced intervals concen trically in said core, countersunk depresof said tubes.

rea ers sions rormed in said recessed seats, and

screws having beveled heads receivable in said countersunk depressions, sald screws beingengageable with threads in the ends A reel comprising a pair of-circular disks, a spacing core therebetween, a plurality of metallic tubes,screw threaded interiorly at their ends,vinserted in said core, said tubes being of lesser length than the core, and countersunk screws insertible through said diskswngageable with said tubes, the heads of said screw-s being substantially level with the surface of said disks and operable from either side of the reel.

4. A reel comprising a pair of disks having a central raised seat containing an opening and a single keyway formed therein, of a relatively soft core centered between said disks, said core having a central opening and a plurality of equally spaced keyways formed therein, fastenings enterable through said disks, said fastenings corresponding innumber and spacing with thekeyways in said core, and meansof securing said fastenings.

5. A reel comprising a pair of QllSkS,"l

' soft core centered between said disks, a plurality of uniformly spaced keyways in said core, a corresponding number of bolts passing through said disks and screw-threaded into said cores, and means for engaging said bolts beyondone of said disks.

In testimony whereof I have signed my name to this specification.
